1. Calculate sfg for water at 100.°C using the Gibbs phase equilibrium conditions and compare it with the value listed in the steam tables.
2. Using the hfg data from the steam tables at psat = 14.7, 100., 200., and 300. psia, calculate the value of sfg at these temperatures from the Gibb's phase equilibrium condition and compare your results with the sfg values listed in the steam tables.
